Flannel is a soft woven fabric made from cotton, wool, or synthetic fibers that has a slightly napped surface. It is a popular fabric choice for shirts, pajamas, robes, and other clothing because of its soft, warm, and comfortable feel against the skin. But not all flannels are created equal when it comes to softness. The softest flannels are made from high quality fibers, have a high thread count, and go through special finishing processes to maximize the fluffiness and coziness of the fabric.
What Makes Flannel Soft
There are a few key factors that determine how soft a flannel will be:
- Fiber content – Flannel made from fine cotton, wool, or microfiber will be softer than flannel made from coarse, low quality fibers.
- Thread count – Flannel with a high thread count (number of threads per square inch) feels softer and more supple.
- Napping – Brushing and napping the fabric raises fibrous nap, making flannel softer.
- Finishing – Softening finishes like sanforization helps maximize the fluffiness of the fabric.
The Softest Flannel Fibers
The fiber content has a big impact on the softness of flannel. Here are some of the best fiber options for soft flannel:
Cotton
High quality cotton flannel made from extra long staple cotton fibers is very soft and breathable. Pima cotton and Egyptian cotton are considered the highest grades of cotton and make exceptionally soft flannel.
Wool
Wool flannel has natural softness and insulation that gets even better with wear. Extra fine Merino wool makes some of the softest and most luxurious flannel.
Microfiber
Synthetic microfibers like polyester and nylon can be made into very soft flannel. Microfiber flannel has excellent heat retention too.
Flannel Fiber Comparison
| Fiber | Softness | Heat Retention | Breathability |
|---|---|---|---|
| Cotton | Very soft | Good | Excellent |
| Wool | Soft | Excellent | Good |
| Microfiber | Soft | Excellent | Moderate |
Optimizing Softness in Manufacturing
It’s not just the fiber type that determines the softness of the final flannel fabric. Manufacturing processes also play a key role:
- A high thread count per inch creates a tighter weave and softer feel.
- Napping or brushing the surface fibers raises a soft nap.
- Sanforization slightly shrinks and thickens fabric to make it feel lush.
- Softening washes reduce stiffness and enhance drape.
- Quality control checks ensure consistency and remove flaws.
Reputable brands pay close attention to optimizing these processes to create the softest and highest quality flannel.
